TI 120 polyester enamel copper flat wire

1)Material:CCC Chilean cathode copper 2)Size:a 0.6-7.5mm;b 2-30mm or OEM 3)Thermal level:120C 4)High resistance for voltage

Polyester enamel copper flat wire is made by flat copper conductor (TBR, TBY1, TBY2), on which coating polyester paint by the paint-srcaping tool or by the felt in 5-13 layers. Based on yielding strength of conduct, it can be divided into soft and semi-hard status, and is an ideal material to produce winding for dry transformer, oil-immersed transformer, generator, motor, reactor, and the other electric appliances. For special requirements of thickness of paint film, please contact us.

Advantages:

1. high heat resistance

2. fine cut-through resistance

3. high resistance for voltage in dry and wet working conditions.
